I meant to say, Pacquiao accepted the fight as the current situation in Philippines fighting the coronavirus pandemic will help the country as we all know that the last match Mayweather earned roughly $275 million and $100 million in total for McGregor.
This amount is too huge given the current situation, and that fight between Conor and Floyd, there was a gate entrance, at the current situation, it's not possible, so the number will certainly go down, at least we should not expect that high, but it's still money.
Gate collection is always secondary. Most of the revenue comes from PPV buys and sponsorship. And since fans are hungry for live action, I would expect the revenue from PPV buys to go up. It may not reach the figure they had during the Floyd vs Conor fight (since the fight involves two non-Americans), but we can expect total revenue upwards of $250 million (with most of it coming from North America and the European Union).
